Abstract
Life course intervention research requires a thorough understanding of complex factors that interact to affect health over time. Partnerships with families and communities are critical to understanding these interconnections and identifying effective interventions. Here, family and community engagement are presented, aligned with the 5 phases of the life course intervention research framework: planning, design, implementation, evaluation, and translation. During planning, the researcher considers their own starting position and what they need to learn from families and the community. The design phase produces a plan for family engagement that is layered, iterative, and includes qualitative methods that will inform life course modeling and the research process. The implementation phase includes administrative actions such as creating opportunities for contributions and providing compensation to family and community partners. The evaluation phase requires measurement of the quality of partnerships with families and community and includes making adjustments as indicated to improve these partnerships. This phase also calls for reflection on the impact these partnerships had on the intervention, including if they made a difference for those being served. During translation, the researcher works with all partners, including families and communities, about follow up steps toward project continuation, replication, or completion. The researcher also works collaboratively in determining how the study results are shared. A holistic approach to health over the life course that is designed and executed in partnership with families and their community can generate research findings with broad practical applicability and strong translational potential.
